Dissapointed with volume bug

Bought this software after reading posiitve reviews. However it is currently broken, and super annoying. Using Itunes 11, and mountain lion, on my Retina Macbook Pro adjusting volume with my B&W p5s while bitperfect is enabled results in headphone audio balance being moved to the left.

Spent hours trying to fix, only to discover that it requires disabling bit perfect, fixing balance( which appears centered while bitperfect is running), and reenabling bitperfect. Seems that system volume cannot be reliably adjusted when bitperfect is running.

Will see if problem occurs with my fiio e10 when it arrives next week and update accordingly.

Update - Worls fine with my external DAC. Considering that software is aimed at poeple with exteranl DACs I have changed rating from 2 to 3 stars.
